T80.82XA vs T86.01
T80.82XA (Complication of immune effector cellular therapy, initial encounter) compared with T86.01 (Bone marrow transplant rejection), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?
Yes, when both are documented. T80.82XA carries an Excludes2 note covering T86.01: “complication of bone marrow transplant (T86.0)”
